Access "Host-based replication"
This article is part of the Vol. 5 No. 10 December 2006 issue of The hottest storage technology for 2007
While the lines of distinction among data protection technologies such as backup, continuous data protection and replication have blurred, host-based replication can play a key role in your overall data protection strategy. The lines between data replication and data protection software products are becoming blurred as storage managers wrestle with the familiar trinity of data protection: centralized backup, disaster recovery (DR) and business continuity. With some industry observers predicting a convergence of backup, continuous data protection (CDP) and data replication software in the next few years, choosing a host-level (server-based) data replication product has become much more complicated. The similarities that host-level replication software products have with backup and CDP products contribute to the difficulty in understanding where one ends and the other begins. For instance, CA XOsoft's WANSync replication software suite includes options that could allow it to fit into all three of these categories. Its WANSync high-availability option (... Access >>>

SAN consolidation strategies
As islands of SANs proliferate in companies, the cost of storage can soar. Sound SAN design strategies allow companies to reduce the number of SAN islands, strengthen a primary SAN, make storage easier to manage and provide more data protection.
Configuring storage for ERP
The "crown jewels" of corporate data are typically maintained within enterprise resource planning (ERP) applications. But for many storage managers, ERP is a minefield of critical information and competing priorities. In this first installment of a three-part series, we look at ways to protect ERP data while improving performance.

Hot technologies for 2007
"Storage" magazine's editors reviewed technology developments, product introductions and storage standards to come up with this short list of must-have technologies for 2007. We believe iSCSI SANs, hardware-based tape encryption, high-capacity disk drives, virtualization and thin provisioning will have the greatest impact on enterprise storage environments.
Quality awards II: EqualLogic named top midrange array
by Rich Castagna
Another Quality Awards dark-horse candidate, EqualLogic PS Series, joins backup winner BakBone in unseating established players for top honors.
- Mobile drive tech could move into data center
There are three distinct architectures of host-level replication software: Windows-only file system, multi-OS file system and multi-OS blocklevel products. Each alternative offers specific features that make it a better fit for some types of data protection.

Recent storage company IPOs remind us that fast and loose spending isn't behind us
Storage Bin: Just when we thought the fast and loose spending of the dot-com bubble was well behind us, a few recent storage company IPOs remind us that we really haven't gotten a lot smarter.

Data backup versus data archiving
Companies should split backup and archiving into two separate initiatives to help them differentiate between copying data for recovery, and retaining data for future reference and retrieval.
Is it really a disaster?
Was it really a disaster after all? It's important to distinguish operational recovery from disaster recovery because the tools and techniques used in each situation can differ significantly.
